A system and method are presented for treating branches of the superior hemorrhoidal artery by photocoagulation using laser energy. The inflamed dilated blood vessels in and around the anal region, often called hemorrhoids or piles, are caused due to a connective tissue disorder, a relative increase in pressure in the superior hemorrhoidal artery and a weakening of the vessels' valves. A suitable treatment system and a method are given for treating such conditions in a minimally invasive manner. The treatment system photocoagulates the branches of a superior hemorrhoidal artery in the anal and rectal regions using laser energy while causing minimal pain or discomfort to the patient. The system is provided with a transparent operational window. The distal end of the fiber and Doppler system channel are at the operational window. The system also includes a viewing window. The post operative recovery is faster than alternative approaches with no complications. In contrast to most other successful methods of the prior art, general anesthesia is no longer required, thereby significantly reducing complications and simplifying treatment. |
